As we know, the PS4 was for the firsts 7 month the faster seller console ever. Then, is back the Wii...

some people predict in lifetime sales PS4 above Wii, some people predict PS4 under Wii... but i think we all agreed to say that PS4 will definitive not sell at Wii level for the first 3 year... so, by end of 2016, how much will be the gap between Wii and PS4?

Wii sales the first 3 year are some like 17 million in 2007, 24 million in 2008, and 21 million in 2009.

So, Wii sold  ~65 million by end of 2009... i think the PS4 will sell around ~50 million by end of 2016, so, i will go with ~15 million gap between PS4 and Wii.

What you think?

PS4 will quickley outsell it because the wii bubble bursted very quickley later on

FOR THE FIRSTS 3 YEAR!?

seems likely to be in the 12-16 million range.

8 to 10 million.

I think the gap will only be around 5 million. PS4 should end this year around 40M and I expect it to sell roughly 20M in 2016. PlayStation Vue will be out US wide, and start its expansion in EU, PlayStation Now will be available worldwide, and Project Morpheus is going to be a huge shot in the arm. Then I also expect a slim model PS4 next year, and a price drop to $299.99. Then you have to factor in the decline of previous gen consoles, and the shear amount gaming content that is comming to the platform.

I think PS4 will be at 55m by the end of 2016, so a 10m gap.

35% think the PS4 will outsell the wii by the end of 2016, sure i see nothing wrong there.

...withouth considering that PS4 must start to sell +500k all NPD...

There's already a sizable lead already and the chart in the OP only goes until april 4th, before MKwii comes out and wii sells 300k every week the whole summer. Then there's huge japanese sales and 4 million december NPD.
